Media Receiver Protection
Several voltages and components are monitored by TV Micro IC3002 on
the BUB board as illustrated in Figure 6-6. Any fault detected by IC3002
will cause the unit to shut down and blink the POWER/STBY LED on
the media receiver. The monitor has dedicated protection circuits and
a flashing LED. Table 6-1 lists the error codes which can occur, what
caused it and a possible solution to remedy the error.
